No. 09/418,224, filed Oct. 14, 1999, which is a continuation-in-part of application Ser. No. 09/272,652, filed Mar. 18, 1999. The entire contents of both applications are incorporated herein by this reference.

BACKGROUND OF THE INVENTION

[0002] This invention relates to paintball guns.

[0003] The game of paintball involves participants carrying guns which fire pellets of “paint” or dye which are fired from the gun and burst upon impact to leave a mark at the point of impact.

[0004] Most paintball guns use a pneumatic system for firing the paintballs using compressed air or other gas. More recently, such pneumatically operated guns have begun to be electronically controlled for greater effectiveness.

SUMMARY OF THE INVENTION

[0005] According to the present invention there is provided an electronically controlled pneumatic paintball gun, comprising monitoring and/or controlling apparatus for monitoring and/or controlling one or more parameters of the gun's operation and alphanumeric means for displaying data related to said monitoring or control on a display panel integral with the gun.

[0006] The display panel is most preferably mounted on the cheek of the gun.

[0007] Embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings in which:

[0008]FIG. 1 shows schematically an electronic apparatus for use in a paintball gun;

[0009]FIG. 2 shows the handle of a gun; and

[0010]FIG. 3 shows a display.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

[0011] A paintball gun embodying the present invention uses a compressed gas circuit supplied with gas from a gas cylinder to eject projectiles in the form of spheres containing paint which break upon impact. The gun is electronically controlled, typically by a microswitch operated upon by a trigger squeezed by a user's finger and the electronics control the firing mechanism and in particular ensure correct timing. The electronics also enable various different modes of firing, such as a semi-automatic mode in which each trigger actuation causes a projectile to be fired, typically up to 20 times a second, or a fully automatic mode in which a single trigger actuation causes a burst of a selectable number of shots. Other parameters such as dwell time, firing rate, number of bursts per second, and so on are also selectable under the operation of the control electronics. A paintball gun of this type is commercially available as the Angel™ gun manufactured by NPF Limited and reference is made to U.S. patent application Ser. No. 09/137,641.

[0012]FIG. 1 shows a control and display apparatus for use in a gun according to the present invention. The apparatus comprises a central processor 1 which typically includes a microprocessor. As described, operation of the gun is initiated by a user depressing a trigger 2 which acts upon a microswitch in known manner. This sends an appropriate signal to fire control/monitoring circuitry 4, which may be at least partially incorporated in the control unit 1 and which can be used to control the rate of fire, dwell time, etc, and alsoto fire the gun when the trigger has been operated, using the mode designated by the user. These modes may be, for example, manual, semi-automatic or automatic modes or other modes as required or as allowed by the rules of the particular event or tournament he is playing in. These operate in known manner.

[0013] A plurality of input buttons 5 a to 5 e are arranged to provide user input to the processor 1 via a user interface 3 and these have several different functions as will be outlined below.

[0014] The gun is powered by a battery 6 which is preferably a rechargeable type and which can charge through a battery charger 7 which has a mains input.

[0015] An integral alphanumeric display unit in the form of an LCD unit 8, driven by an LCD driver circuit 9 is connected to the processor and this displays various types of data and information. Preferably, a back-light 10 is also provided to enable better viewing of the LCD unit but which back-light may be turned off when required. The alphanumeric display need not necessarily be an LCD display.

[0016] Various other pieces of apparatus, sensors, etc, may be added to the control unit and non-limiting examples of these are shown in FIG. 1. There is shown a temperature sensor 11, a timer 12 and a vibrator 13. The timer 12 can be used for various purposes such as for timing a paintball game and for an alarm function and the vibrator 13 may be used as the alarm indicator for the timer 12. In addition, an infrared link 14 is provided which enables programming of the control unit, or by directional data exchange, to take place from a remote PC or other device fitted with a similar infrared unit. Infrared communication devices are well known. A serial link, e.g. RS232C, or other communications link may also be provided.

[0017]FIG. 2 shows the grip frame part of a paintball gun. The user holds the grip in the normal manner and squeezes the trigger 2 to fire the gun. As shown, the gun is radically different from previous paintball gun designs in that an LCD display 8 is integral with and incorporated into the gun, in this case on the cheek of the grip frame 15. It could, however, be mounted in any other position/disposition on the gun itself. The control buttons are also distributed on the grip frame. Three of the buttons 5 a, 5 b and 5 c are mounted in a recessed portion where they are always accessible. The remaining buttons in this embodiment are mounted under a cheek plate (not shown) which is screwed or otherwise attached over the cheek, possibly using anti-tamper means, or tamper-indicating means such as seals, and thus are only accessible when the plate is removed. This is because these buttons are used, as described below, to alter various functions of the gun which affect its performance, rate of fire, etc. In many events, the rate of fire or other gun parameters must be set before the game begins and cannot be altered once the match is underway. By being mounted in an inaccessible position, these buttons achieve this objective.

[0018] The various functions alterable and displayable on display 8 are as follows:

[0019] Various values and words are selectably displayed by a six character alphanumeric display 24 and a plurality of fixed words/characters which are illuminated as required. A battery indicator 20 is displayed at all times and goes from blank to full (all four segments displayed). When down to about 25% power level the last segment only is displayed, and this flashes indicating low power status.

[0020] A mode indicator 21 displays the mode of firing and may show single characters or numerals such as A, B, C, 1, 2, 3 etc. Modes are displayed at all times. The mode of firing can only be changed by one of the normally inaccessible tactile switches 5 d or 5 e. The modes available may be, for example, SEMI: (1 shot; 1 trigger pull), BURSTS: (a 3, 4, 5, 6, 7 or 8 shot burst per trigger pull), ZIPS (3, 4, 5, 6, 7, 8 shot bursts at a rate of 8.75 shots/sec max). The MROF (Maximum Rate of Fire) function will display 8 when in the ZIP modes.

[0021] The vibrator may work in a timer mode for indicating, for example, 5 min intervals by actuating the vibrator for 3 secs. Note: if the ‘V’ mode is selected the ‘V’ is displayed on the LCD. Switching the vibratory alarm ON or OFF is selected from a sub-menu function

[0022] Temperature may be displayed in ° F. or ° C. by the main alphanumeric display 24. A temperature icon is only displayed when the menu calls for it. Temp mode can be selected from the menu; Changing from Centigrade to Fahrenheit is selected from the submenu.

[0023] A trip meter is a shot counter that can be re-zeroed by the consumer. Trip can be selected from the menu. Resetting to zero is selected from the sub-menu.

[0024] A ROF (Rate of Fire) function may measure a string of shots over a selected (eg 1 second) period. The first shot starts the counter for 1 second, any shots that occur in that period are registered on the display. Then the display will not accept any input for a 3-second period. During this period the display will also flash before an additional cycle may start. The ROF mode can be selected from the menu. The data is constantly updated and so no sub-menu is required.

[0025] The display can accordingly display not only a desired rate of fire, but also the rate of fire actually achieved by the user, which can fall well short of the desired rate of fire, or could even exceed it for a very skilled marksman. Furthermore, competition rules may set an upper limit on the rate of fire, and this upper limit may be programmed in and displayed on the LCD display (MROF). More details are set out further below.

[0026] To power off the gun a tactile switch on the grip must be held for 1.5 seconds which shows the whole display for 2 seconds. Then the display shows the word “SAFE” and the back light switches OFF. The gun cannot fire in the safe mode but the battery meter is still displayed. An automatic power off function may be provided which powers off the gun if no shots are fired for a predetermined period, e.g. 60 minutes.

[0027] A unique ID number may be programmable into the gun by the manufacturers or suppliers. This number may affect, e.g. restrict, the modes it is possible for the gun to be fired in and can render the gun less likely to be stolen.

[0028] Numerous fault codes can be displayed, for example Fault 1, F1=Over temp=38° C., F2=Under temp=0° C., and so on. The fault can be selected from the menu. Should more than one fault be present the display will alternate at 2-sec cycles. The faults will only clear from the display when the fault condition is removed.

[0029] Dwell time may be displayed, e.g. in millisecs=e.g. 0:20=20 ms. Dwell is changed via a tactile button and scrolls from 12 ms to 25 ms.

[0030] MROF displays the rate of fire as shots per sec, e.g. 12=12 shots/sec. MROF may be selected from the menu but can only be changed via one of the normally inaccessible tactile buttons on the board. In one embodiment the range is 5 to 20 shots per second.

[0031] Note: If a mode of fire has a preset rate this will be displayed under the MODE function and cannot be adjusted whilst in that mode.

[0032] A cycles counter is a grand total shot counter that cannot be reset by the consumer, only by the suppliers of the gun or other authorised person.

[0033] A TRIP counter is provided, which is a shot counter that can be zeroed by the user or consumer.

[0034] A timer is a countdown timer which can, for example, count down from 60 min. At the end of the count the vibrator alarm may be activated for 10 seconds. The timer can be set in 5-min increments, i.e. OFF, 5, 10, 15 etc. A sub-menu allows changes. The settings must remain in the memory even after power has been removed.

[0035] The display may also indicate test modes and a BACKLIGHT ON symbol 22 is included. Additional functions displayable include, inter alia, velocity, average velocity, gas pressure and gas usage, for example.

[0036] In one embodiment DWELL, MROF, MODE and TIMER functions are stored in non-volatile memory since these settings must be retained even when power is removed.

[0037] The button functions may be as follows in one embodiment.

[0038] Button 5 a

When gun is in the “-live-”/timer ready status, timer starts when first shot is fired then the display will show the timer counting down. The arm will go off prior to time up. This feature allows the players to know when the game end is near and that they have a final opportunity to bring the game to a conclusion. Display “-safe-” when off and switch 5 b is now active and timer stops. Battery status to be displayed at all times; mode status to be displayed at all times even when “-safe-”.
